AnderbergManufacturing Co., Los Angeles, Calif., a corporation of CaliforniaFiled Mar. 9, 1960, Ser. No. 13,877 3 Claims. (Cl. 16-138) Thisinvention relates to window mounting devices, and included in theobjects of this invention are: Y

First, to provide a window mounting device which is particulanly adaptedfor easement type -windows wherein the window is pivoted about avertical axis; but which may be emplo'yed to a horizontal axis.

Second, to provide a w-indow eliminates the need of hinges, a mountingdevice being disposed at the top, bottom, or at opposite ends of thewindow, and so arranged as to vbe substantially concealed when thewindow is closed.

Third, to provide a window mounting device which incorporates a novelfriction slide, so arranged as to per-mit the windowto be opened andclosed smoothly but offering sutlicient resistance to enable the windowto remain fixed in any position.

With the above and other objects in view, as may appear hereinafter,reference is directed to the accompanying drawings in which:

The window mounting device Iincludes a base strip 1 formed of sheetmetal. The base strip includes an upturned margin 2, the upper extremityof which is folded upon itself to form a downwardly directed ordepending flange 3. Between the upturned margin 2 and the flange 3 thereis defined an upwardly directed channel 4. The margin of the base strip1 opposite from the upturned margin 2 is folded upon itself to form areinforced edge or track 5. Screw holes 6 are provided at convenientlocations along the base strip 1 so that it may be fastened to themargin of a window opening, as shown in FIG- URE 1.

The base strip 1 is adapted to support `a slide 7 which includes a baseplate 8 of sheet metal having an upturned flange 9 at one margin, whichis adapted to extend upwardly into the channel 4. The ybase plate 8overlies the base strip 1 contiguous to the folded or reinforced edge 5as shown in FIGURE 6, and is provided with an upturned lug l0. Betweenthe lug 10 and the depending flange 3 is positioned a friction shoe 11.The friction shoe is in the form of a rectangular block having at itsside which confronts the flange 3 a pair of spaced rudimentary pivot awindow or a transom about sectional view through mounting device whichbosses 12. The upturned lug 10 receives a screw 13 which may bescrew-threaded in the lug so as to lbear against the friction shoe 11and force the friction shoe against the flange 3, drawing the upturnedflange 9 against the back side of the flange 3.

The ends of the base plate 8 are provided with slightly raised bosses14. A cover lplate 15 overlies lthe base plate 8 to retain the frictionshoe 11 in place, the cover plate being notched to clear the upturnedflange 10 and the screw 13. The extremities of the cover plate 15overlie the bosses 14. Rivets 16 and 17 join the cover plate to the baseplate 8. The rivet 17 is of greater length than the rivet 16 and alsoserves as a pivot pin for a mounting lever 1.8. v l

The mounting lever 18 is provided with a downwardly offset end 19 whichreceives the pvot pin or rivet 17. By interchanging the rivets 16 and17, the position of the mounting lever 18 relative to the slide 7 may bearranged so as to provide a left or a right side mounting device. v

The mounting lever 18 is provided with suitably located screw holes 20which are utilized for the insertion of screws to secure the mountinglever to a side of a window W, confronting the side of the Windowopening at which theV base strip 1 is located.

'I'he mounting lever 18 is provided with Ian intermediate offset portion21 to accommodate the head of a pivot rivet 22 which journals one end ofa strut 23. The other end of the strut 23 is connected by a pivot rivet24 and a washer 25 to the base the normal position o-f the slide 7. Thewindow mounting device is used as follows:

The mounting device is used in pairs. If the window is to be mounted formovement about a vertical axis, the base strips 1 of a pair of mountingdevices are secured to the top and bottom sides of a window opening, inwhich case the central portion of the base plate 8 of the lower sliderides on the folded margin '5, and the mounting levers 18 are secured tothe adjacent sides of the window. When the window is in its closedposition, the mounting levers 18 overlie the base strips 1, Kas shown inFIGURE 2. When it is desired to open the window, the margin of thewindow opposite from the margin located between the mounting levers 18is pushed outwardly. This movement not only pivots the window about avertical axis but also moves the slides 7 away from the adjacent side ofthe window opening, as indicated in FIGURES 1 and 3. In fact, the windowmay open to a position normal to the window opening or beyond thisposition so that the normally outside surface of the window isaccessible for cleaning.

While a particular embodiment of this invention has been shown anddescribed, it is not intended to limit the same to the exact details ofthe construction set forth, and it embraces such changes, modifications,and equivalents of the parts and their formation and arrangement as comewithin the purview of the appended claims.
